Tough 3D printing resins

While FDM technology of 3D printing can use traditional industrial plastics like ABS and Polycarbonate, resin 3D printers require special photopolymer resins that harden (cure) under UV light. Most 3D printing resins are either epoxy-based or acrylate-based, the latter used more often in desktop printers. Many thinks of resin 3D printed parts as fragile and […]

Gradient vector, Hessian matrix and Quadratic forms

Gradient vector: If the partial derivative of a function f(x) (function having $n$ variables) with respect to the $n$ variables $x_1$, $x_2$…..$x_n$ at a point $x^{\star}$ is taken, then that partial derivative vector of f(x) represents the “gradient vector” which is represented by symbols like $c$ or $\triangledown {f}$, as: $\mathbf{c}=\nabla f\left(\mathrm{x}^{*}\right)=\left[\begin{array}{c}\frac{\partial f\left(\mathrm{x}^{*}\right)}{\partial x_{1}} \\ \frac{\partial f\left(\mathrm{x}^{*}\right)}{\partial […]
